timberwolf roller blade change

[aspenarb]

Done the blades on the tw rollers today. I cant find the thread but someone was having grief getting the bolts out so here is how we do it.

 

Take off the hopper , the hydraulic motors bolts , the grease nipples the other side and the bearing support bolts.

 

 

Normally reveals other gremlins like this wire that was about to chew though the motor seals:thumbdown:

 

 

Blades have lost their newness and were not pulling in the smaller stuff.

 

 

These bolts rarely undo so dig out the ends and plugweld up the allen head of the bolt

 

 

 

Then plug weld a 12mm nut to the top of the allen bolt

 

 

19mm spanner and they are straight out.

 

 

Jobs a goodun , should only take about half an hour to get all the bolts out, the heat melts the original loctite and helps release the thread from the rust.

you need to treat them to a nice new tw230,

Gave 150 a new set of roller blades today could not shift the bolts so added a weld and hit with hammer and chisel had one that was not going to play ball, landed up building up weld to get more heat then hit it Allen socket would not fit so just welded tab to it and unwound it with adjustables.

I had this problem which was solved by heating the whole lot up on top of stove so locktite softened and they came undone easily

Had the same issue. Welded a bolt inside the hex head and undone them like that

Sorry to latch onto the back of this thread but I have the exact opposite problem. The lower roller bolts keep coming loose about every 5 to 10 hours of use. They work out a bit and slow then stop the roller from working.  I have tried all sorts of Locktight / tite and in particular  No 243.  I am considering in my desperation using Araldite!  Any ideas from this forum as to what to use?

Have you cleaned out thread holes properly before using new locktight. 

[Dan Maynard]

Possibly the threads are now worn, loctite is a poor gap filler. Araldite I guess might work, could give it a go as it will be removable with heat later.

If it's the threads worn then I guess more engineering required or change the roller shaft for new.

Sounds like the one of the roller motors is goosed and the blades are beating each other up.These motors are piped in series, as in what is the return for one motor is the feed for the next, if only one of them slows it means fluid is pumping straight through it ( fecked). Worth checking, wedge the bridge up to give the rollers some space and tipex them, then run the rollers to see if they stay in synch. They should be turning at the same speed.

I’ve said it before and I’ll say it again, you’re a supremely useful fellow to have on here.
